M 103Quite a small cluster, 6arcmin, in Cassiopeia, near Ruchbah, the blue star in the photogrph. Not very imposing, though mag 7.4, but well shaped and in a fine star field.
Taken with an M25C in the William 98FLT. The exposure was 16x120sec unguided. Acquired and pre-processed in AstroArt and finished off in Photoshop.
